A heat dissipating device comprises a plurality of fins. An upper side and a lower side of each fin is folded with folding sheets. Each of two sides of each sheet is protruded with a buckling ear. The buckling ear is formed by a triangular sheet and a support plate. The support plate is connected to one apex of the triangular sheet and the folding sheet. A hole is formed on the folding sheet and is located behind the buckling ear. The shape of the hole is corresponding to that of the buckling ear. A tenon is formed at two lateral walls of the hole and a middle section of the tenon is protruded with a semi-round section. Further, the buckling ear may have a T shape or the triangular sheet can be replaced by a round sheet.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A heat dissipating device comprising: a plurality of fins; an upper side and a lower side of each fin being folded with folding sheets; each of two sides of each sheet being protruded with a buckling ear; the buckling ear being formed by a triangular sheet and a support plate; the support plate being connected to one apex of the triangular sheet and the folding sheet; a hole being formed on the folding sheet and being located behind the buckling ear; the shape of the hole being corresponding to that of the buckling ear; a tenon being formed at two lateral walls of the hole and a middle section of the tenon being protruded with a semi-round section; wherein in assembly, the buckling ears of one fin are buckled to the holes of another fin so as to assembly two fins together; the tenon serves to buckle the buckling ear to the hole; more fins are assembled by the same way; the heat dissipating device can be assembled to a computer central processing unit.
